This invention relates to improvements in devlces for twlsting'wlres and has reference more particularly to a device intended for use in sealing candy pailsandsimilarcontainers in-which'the cover is held in place by means of two wires whose ends are secured to the pail portion.

This 4 invention briefly described, Consists of a base having two spaced brackets extending upwardly therefrom. A pinion is ro tatably mounted between thebrackets near the bottom of the'base. A sectobsh'ap'ed gear wheelie located between the twoarms' and pivotallyjattached to the. latter; "This gear is in mesh with the pinion so that when it is turned about its pivot, it will rotate the pinion. The pinion is provided with a slot or opening extending inwardly to a point'slightly beyond its center. This opening is for the reception of the two wires that are to be twisted. A handle is secured to the gear wheel and serves as a. means for rotating the same; The end of the-handle is provided with hooks for engaging one of the wires and moving it into the opening in the pinion. ,Holding members are secured to the brackets and are provided with notches ontheir lower surfaces and serve to hold the --wires after they have been moved into the'opening in the pinion. The pinion is first rotated inonedirection to the extent of its movem'ent and the two wires are then introduced into the slot, after which the pinion is rotated in the opposite direction and twists the wires.

Having thus briefly; described the invention, the same will now be describedin detail, and for this purpose reference will be had to the accompanying drawings, in which the preferred embodiment thereof has been illustrated, andin which: I,

- Fig. 7 is a top plan view of a candy pail that has been scaled by means of this device. I In the drawings reference numeral 1 represents the base which is preferably made of two parts and has a removable portion 2 and two upwardly extending spaced brackets 3. The part 2 is secured to thepart 1 by means of screws 4 and isprovided witha recess 5 in Which is locateda pinion 6. This pinion is provded with trunnions 7 at each end and is also provided with a slot or opening 8 that extends inwardly to a point beyond the center, as shown in Fig. 5. The trunnions are mounted for rotation in bearings between the member 2 and the guide members 9. Pivotally connected vto the upper ends of the brackets bywmeans of a pin 10 is a sectorshaped gear wheel 11 This gear wheel is operatively connected'with the pinion; in the manner shown in Fig. 5. Secured to the gear wheel is'a handle 12. This handle has-two parallel sides 13 and 14 connected by a mem ber 15, so that its 'cross section is sub'stantiah ly U-shaped. This'handle is pivoted on pin 10 and extends outwardly beyond the periphs cry of the gear where it terminates in-two ends 16 that are provided with hooks=17on the side adjacent the pinion.

The gear is provided with a longitudinal opening18'for the reception of a pin 19 that extends through V the two sides 13 and 14. This pin connects the handle with the gear and permits a slight relative movement between the two. posed between the handleand the gear is a spring 20 which is shown in Fig. 5.. This spring tends to hold the handleand the gear Inter- S in a certain positon, but permits the handle to move relative to the gear after the gear has come in contact with the stop 21. Se cured to the outsideof one of the brackets is a lever 22. This lever is pivoted between lugs 23'and has a plunger 24 attached to its end in the manner shown in Fig. 3. A spring 25 9 serves to movethe plunger inwardly so'as to bring it into the path of the gear 11. Pivlocated slightly to the front of the center of the pinion and serve to receive the wires and hold them in place in a manner which will hereinafter be more fully described. The rear ends of the members 26 are connected by means of a bar 271 as shown most clearly in Figs. 4 and 5. This bar has an opening through which the rod 28 extends. Rod 28 is provided with an abutment 29 against which one end of the spring 30 abuts, and another spring 31 is located between the lower surface of bar 271 and the upper surface of nut 32. Secured to the upper end of rod 28 is a connector 33 having its upper end pivoted at 34 to the handle 12. lVhen the handle is in the position shown in Fig. 1, in which it engages the stop 21 spring 30 is under compression and the holders 26 are held with their front ends elevated but when the handle is 'moved to the position shown in Fig. 2, the holders have their lower ends down besides the ends of the pinion so that the hooks in the ends of these holders are in position to hold the wires that have been indicated by reference numerals 35 and 36.

The extent of the movement of the gear wheel is limited by the stop 21 with which it is engaged by the handle when the partsare in the position shown in Figs. 2 and and by the plunger 24 which is interposed in the path of the gear wheel when the parts are in the position shown in Fig. 1, in which position the gear and the handle can move as a unit through a small angle since the stops are so located that when the gear engages the stop 24, the handle is spaced a short distance from stop 21. The gear wheel 11 is permitted to move through such an angle that it will rotate the piniontwo complete turns and a slight amount in excess of this. Although two turns is believed to be preferable. a larger number of turns can be employed if found desirable.

With the parts assembled in the position shown and described, we'will now assume that the device is to be used for sealing a candy pail provided with two sealing wires 35 and 36 as shown in 7. The ends of the sealing wires are attached to the pail portions and form loops that are bent over the top of thecover. lVith the parts in the position shown in Fig. 1 the device is inserted underneath wire 35 which is moved into the opening in the pinion. The plunger 24 is then withdrawn by pressure on the han dle 22 after which handle 12 is moved upwardly from the position shown in Fig. 1 to that shown in Fig. 2. During this movement the hooks 17 engage the wire 36 and brings it into the position shown in Fig. 2. When the parts are in the position shown in F igs. 2 and 5, the gear has engaged the stop 21'and any further movement of the handle compresses the spring and when this oc curs the wire is brought into the opening 8 in the pinion and back of the shoulders of the hooks in the holding members. The wires will now be held in place and when the handle is moved from the position shown in Fig. 2 to that shown in Fig. 1, the pinion will be rotated in a counter clockwise direction through two complete turns, thereby twisting the two wires together in the manner shown in Fig. 7 In order to compensate for the resiliency of the wires, the pinion is rotated slightly beyond the position shown in Fig. 1 and then returned so that the wires can be readily removed without the force that would otherwise be required. Guides 9 pro- 'ject in front of the pinion and serve to direct the wires into the notch in the pinion.

From the above description it will be seen that the device described is very simple and can therefore be cheaply made. The operation is positive and the construction is such that, the device will be able to resist all the strains to which it will normally be exposed.

I wish to call particular attention to the lost motion connection between the gear and the handle and to the fact that the pinion is rotated through a certain number of completeturns plus a small angle so that it will remove the strains due to the resiliency of the wire, and therefore permit the free removal of the device from the wires.
